. To all whom it may concern.' A 'l Be it known that I, EMIL G. Jason, a cit-1- zen lof the United States, residing at Newvlark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Presses; and I do hereby declare the following to be a f'ull', clear,.and exact description` of the invention, such as .will enable .others skilled in the art l towvhich itzappertains to make and usefthe same, reference being had to the accompanying drawings, andlto figures ofreferencemarked thereon, whichform a part of thisl specification. i This invention relates to a press which 1s, providedwith dies between which material 1sv to be stamped or`molded, andwh1ch d ies are adapted yto receive heating and 'cooling `mediums to alternately heat and chill the dies, thepress havingmechanism. for alter. nately permitting ythe admission of the mediums to the dies. j T he invention further-provides a press of this kind with means vfor regulating .'the speed of the press' to regulateithe time the dies are together, in other-words, ,to submit the material to the action offthedies -a prejH determined space of time'and to control the' regulating means by a thermostatic device, which thermostatic device in turn Vis ini fluenced the heating and .cooling-.me-` diums which `are used in the dies.

In some materials when they Kare used in presses it is necessaryr to stamp them in warm or heated condition, or to have. the dies heated, and after they are pressed inl their warm condition to the required shape, the material requires cooling to either set the material in its molded shape and to make it hard, or to' give it a polished iinish. This is particularly true of a great many plastic materials, and to automatically regulate the heating and 'cooling of the material and to insure the contact of the dies with the material for 'the required space ofv time, this press has been devised, The yinvention is somewhat diagrammatically illustrated in the accompany1ngdrawing, in whichv Figure l is a view of a press of Very simple form with the thermostatic means for controlling the operation of the press. Fig. 2 is a view of a modified form of means for regulating the starting and stopping yor the speed of the press,and Fig. 3 isa viewgof of thirds means.

The valve 26 alternately admits the heating and cooling mediumsto bothjpipes 24 and 25 and is preferably operated from the die-operating mechanism. To accomplish this Iv illustrate the pulley 29 of the shft `1% which has a belt 30 which in turn passes over the pulley 31 of the shaft 32. An eccentric 33 rocks the arm 34 whioi has a segmental gear thereon in meshwich the pinion 35 of the valve. .The thermo-static meehanism 36 is connected'by the pipes 37 and l38 with the dies so. that the heatingnand cooling mediums are conducted to the ex' ansible element 39 of the thermostaticmec `enism, the expansible element bein fixed at one general type of press shown end iin-a support 40 and having its' niomhlefll 1911, and I` alsoprefer lend 41 disposed that it can used to vregulate the speed of thel press in a 'manner' to be 'hereinafter described. -I preferv to `make the expansible' element hollowl to re ceive the heating and cooling-mediums vand to be provided with an'outle't 42 connected with an outlet pipe 43 which in turn is con-.

nected with the waste-pipe The expansible element 3 9.' is connected withA a lever, 45

pivoted at 46 and having its free; end operatively connected with 'a rod y47. In I1`ig-1` the 'rod 47 forms the stem of a' valve 48150` ,that when the 'valve' is-"opeluidunder z pressure, such as Iair, can pass from the inlet 49 ofthe pipe 50 to the air-operated clutch- 51 mounted on the main-shaft 21 and adapted to be thrown into and outl of operative.

The operatlon of the press 1s as followsg-j- Assuming that th'epress is in motion and starting from the position shown Ain Fig. 1,

Y -the arm 15A will beoperated by the cam 16 loovaline the toggle-levers 11 and'v Aforce the die 13 incontact with the die 14, andv at the same time the valve 26 is operated to' admit gether, and the materialwhich is'usually fed to the press-heated,l or if. it is not, is heatedv by Contact with `the dies, is molded into the'.

required shape or configuration. The heatlng medium passes through the dies and through the pipes 37'and 38 to the thermothroughvthe pipes37 and 38 `to the thermo- I j to the thermostatic device, shortens, the eX- static device' 36 and heats the expansible element 3 9 so that it becomes longer and pushesthe short end of v'the lever' 45 againstthe spring 52 which abuts on the 'nut53 onthe rod 47 and closes the valve 48 vas vshown in Fig. 1. This releases the Clutch- 51 and the press stops, since the clutch 51 is not under pressure. In thc meanti-me, however, while this heatingV medium has been traveling static device, the valve has been turned'ito admit the cooling medium which new -follow/s the heating medium and drives the heating medium before it through the dies, chills the dies through the pipes 37 and -38 pansible element, 'swings the lever 45- against the adjusting screw54 on the rod 47, opens the valve 48, the clutch`51 is under pres- Sure and is thrdwn into .Contact with the drivingpnlley 22-and the press'again begms to `operate and the 'dies fire drawn apart.. VVheIrthe dies are apart, lopportunity is presented for removing the stamped material, putting' fresh material between the dies, the valve 26 has rotated far enough tol again admit heating medium tothe pipes and the'dles, and the sequence f the oper-' x ation of the different elements is repeated asv above described.

.It willthus be seen that-an automatically operated press is-produced which stops and.

Losa-ikea 'starts automatically at predetermined times, requiresgnomanual manlpulation, and 4mvsu'res the heating and cooling of the material thatis pressed. The springz52 1s' installed totake up lany excess expansion of the expausibleelement 39 and permit' the lever 45 to swing after the valve 48 is shut. y I install pipes 55 and 56=connectivng the pipes 38 and 37, respectively, to thev Waste-pipe 44 when erated by an electric motor 61. which is in circuit with the wires 62 and 63 whichI are 'ledfrom any suitable source of power. 4One vtermir'ial 64 of a switch lis fixe iand'thef otherterminal 65 is mountedont e rod47 which is swung as before, byfthe leve1 45.Y This .form illustrates one'meaiis of` electri-' cally stopping and starting' the press, inlieil In Fig. 2 I show a modifica-tion"ofv the with a gear' 59 in mesh vwith a gear 60 op- Aofthe' pneumatic "means -show'n 1n Fig. 1,9" and the mechanical means show-n' in-Fig.'2.
